Aldon's Gatemaster openers are compact, simple-to-use manual tools for hard-to-open railcar gates.
Through planetary gear reduction in the Gatemaster head, the worker's handle effort is multiplied 18-1/2 times — a considerable mechanical advantage. Maximum torque output of 3,200 lb.-ft. (enough to open almost all gates) can be achieved by only 173 lbs. of handle effort.
